McPherson Wash meanders across the arid terrain of this Yuma County landscape, defining the natural drainage patterns of a region shaped by ephemeral watercourses. This area, largely defined by the grid of the Public Land Survey System including t2s r18w and t3s r17w, remains relatively undeveloped, serving as a corridor for travel through the desert. The presence of Kofa Deep Well in the northeast suggests the critical importance of localized water sources for cattle or transit in this environment. Transportation is anchored by two primary routes, King Rd and Wellton Kofa Rd, which provide access to this isolated interior. The topographic contours reveal the subtle shifts in elevation that guide the flow of the wash during infrequent rains, offering a clear view of the natural topography as it existed in the early 21st century.
